Posted on May 18, 2018 at 12:11Hello ,I am toggling a gpio inside the timer ISR . the timer ISR triggers for every 1 sec. Actually i am not able to see perfect 1 sec of gpio toggling . it also differs at different AHB frequency . i have included 2 c...
Resolved! STM32 MIPI checksums
Posted on May 19, 2018 at 16:21So, I am using STM32F769xxx to run MIPI-DSI display. On the display's datasheet there are power on and off sequences. I am able to get display on and off (so commands are at least somewhat OK), but colors and data on l...
Migrate from STMF4 to STM32F7 (configuration of memory mapping and bootloader)
Posted on June 02, 2017 at 09:41Hello , I'm a trainee and my project is to migrate from stmf4xx to stm32f7xx , so i was compile the all project using stmf7xx library on keil uvison 5 ,and fix all error due to incompatibility of these two microcont...
Resolved! Strange behavior of Port G and SPI of STM32L4+ (STM32L4R7ZIT6-144 Pin LQFP Package)
Posted on May 19, 2018 at 06:04Hi !I am using STM32L4R7ZIT6-144 Pin LQFP Package on Keil-MDK, So far all other GPIO ports SET/REST test is normal except Port G with its associated SPI configuration which is neither getting SET nor RESET on push pull...
VREF+ in STM32L1xx
Posted on May 18, 2018 at 00:53Dear all,I have question regarding the VREF+ please. My understanding is that in STM32L we only have one VREFINT which is about 1.2xx Volts and this is not a reference Voltage to the ADC. It is directly connected to ...
Left and Right alignment in DOR (DAC STM32F103RB)
Posted on May 18, 2018 at 22:27What is the purpose of Left and Right Alignment of data in DAC?Secondly, In DAC_DHR12L1 do we need to manually shift the bits to the left to get them to right place or does it happen automatically?#dac #stm32f103rb
Some registers are not written in debug!
Posted on May 18, 2018 at 15:32Hi everyone,I'm not using CUBEMX or HAL drivers, i'm programming manually on stm32f746g disco board. When i build and debug, some registers are configured but some are not configured. If i restart the debug without ext...
STM32F407VG + 4 bit SDIO + DMA does not work probably
Posted on April 27, 2018 at 19:33 Hi, I am using the STM32F407VG and try to read an SD Card over SDIO in 4 bit mode. I have downloaded the fatfs driver from this site: https://community.st.com/external-link.jspa?url=http%3A%2F%2Fstm32f4-...
